The ORR 1802 is a compact dual channel fiber optic receiver designed to combat the restrictions involved with the distribution of uncompressed broadcast quality video signals over long distances. The yellobrik OCM 1892 9-Channel CWDM Optical Mux/Demux (1450 to 1610nm) from Lynx Technik AG is a compact passive unit designed to send and receive up to 9 individual signals over a single fiber link. The module has an UPG (Upgrade) port to cascade into other optical multiplexer/de-multiplexer units to expand the total number of multiplexed signals. The module can be used as a standalone or integrated into the optional RFR 1018 1/2 RU 19” rack frame, which can accommodate up to 9 channel modules. The unit is suited for use with CWDM yellobrik fiber modules.
